I've been using screen for years, and just switched to tmux since so many people have been raving about it. The reasons I switched were:

1/ Configs for status prompt were easier to grok

2/ Actively maintained. I used to use vertical split all the time and tmux had that where as gnu screen required hack patches.

If you only want persistence, screen, tmux, dtach do pretty much the same thing.
